That he would grant you, according to the riches of his glory. The standard or measure of the Divine giving is brought into view. "Riches of his glory" is a more emphatic expression than "glorious riches," though substantially the same in meaning.
God's standard of giving is liberal, bountiful, overflowing. An image of the riches of his glory is seen in the starry heavens, which proclaim at once the vast riches and surpassing glory of God. Or in the beautiful appearance of an autumn sunset, where the whole sky is flecked with clouds brightened into a sea of glory.
In prayer, it is both useful for ourselves and glorifying to God to recognize his bountifulness—to remember that he gives us a King (2 Samuel 24:23). To be strengthened with might by his Spirit in the inner man.
The inner man is the seat of influence, but with us it is the scat of spiritual feebleness. Most men may contrive to order their outward conduct suitably; but who has control of the inner man? Faith, trust, humility, love, patience, and the like graces which belong to the inner man, are what we are weakest in, and what we have least power to make strong.
In this very region it is sought that the Ephesians might be strengthened with might by the Spirit. The gift of the Spirit is available for this very purpose for all that ask him.
